Brewerton, N.Y. -- Interstate 81 is open from Brewerton to Mexico, but remains closed between Mexico and Watertown, according to the State Department of Transportation.

Oswego County was expected to be hit with three to six inches of snow by 6 a.m. Wednesday, then six to 11 inches throughout the day and an additional four to eight inches tonight, the National Weather Service said.

On Monday night, Gov. Andrew Cuomo declared a state of emergency and ordered I-81 closed from Watertown to Brewerton ahead of the snowstorm. Accidents Tuesday extended the highway's closure to the Canadian border.

The stretch of highway from Brewerton to Mexico was reopened Tuesday night.

The state also reopened the Thruway in Western New York Wednesday morning. It had been closed from Rochester and Pennsylvania.
